T 0 all whom it ay concern:

Be it known thatl, Jonn YLKING, 'a citizen of the Unitedyfitates, residing at llansdowne, in the county of Delaware and State of Pennsylvania, have invented new and useful lniprovements"in Air-Feeding Devices for Coal Stoves,of whichthe following is a specification.

My invention relates to. a new and useful improvement 1n air feedlng devices for coal stoves, and has for its object to provide an exceedingly simple and effective device of this description which may be readily applied to the round eyes of plates of a stove as well as the cross plates and with equal facility may be applied to any other portion of a stove so as to inject air at a high temperature adjacent the fuel bed for intensifying the oombustionof said fuel.

A further object of my invention is to providea simple and effective means of attaching the device whereby air will have free passage thereto.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawing forming a part of this application. in which 2-- i Fig. 1, is a plan view of a portion of the top of a cook stove showing the application of my improvement to several parts thereof.

Fig. 2, is a section at the line 2-2 of Fig. 1. v i

Fig. 3, is an enlarged plan view of my improved device.

Fig. his a side elevation of Fig. 3.

Fig. 5, is a plan view of the deviceshovw ing the attaching screw therein.

Fig. 6, is a central section of the device shown as attached to some portion of the stove. p

In carrying out my invention as here embodied, 1 represents a hollow drum having two sections of its periphery formed at angles to each other, the outer surfacethereof being divided into facets 2 for the purpose hereinafter set forth. With this drum is preferably formed a hub 3 having a threaded hole 4-. therethrough leading to the interior of the drum adaptedto receive'the threaded portion of the attaching screw 5 which latterv has a small passageway 6 formed therethrough, said passageway terminating in the slot? in the screw head. By this arrangement the drum may be readily attached toany portion of a, stove 'p'lateby simply forming a hole through the part to which the device is to be attached 5 and passing the attaching screw 5 through said hole and threading it into the hole i in the hub. This construction makes it possible and practicable to attach the device to a stove plate regardless of projections or ribs. which may be formed upon the underside of said plate.

8 represents a series of small holes drilled at right angles to the surfacesof the facets on the lower portion of the drum and there may be as many of these holes as desired either one for each facet or a lesser number. By forming the exteriorof the drum as before described the drilling of the holes 8 is greatly facilitated since the facets upon 80. the upper portion of the drum serve as bases upon which to support the drum while the holes of the diametrically opposite facets are being drilled, which will give the proper angle? to theholes as will be readily understoo i One of these devices being attached to some suitable part of a stove the air will flow in through the slot 7 and hole 6 to the interior of the drum and be there heated and expanded and projected from the holes 8 in fine jets at a slight downward angle and so intermingle with the gases arising from the coal bed as to greatly increase the intensity of the combustion of said gases and thereby greatly economize in the use of the fuel for a given amount of heat produced. The construction of the drums as here described facilitates the heating of the air passing into said drums and also greatly increases the efficiency of the air projected therefrom since said air being projected in jets from a common center produces a cyclonic action in the gases arisin from the coal bed, and in practice several of these drums are utilized in each fire box providing common centers of agitation and the process of properly intermingling the heated air and products of combustion is greatly facilitated.

Of course I do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is 1. As a new article of manufacture, an air feeding device consisting of a drum the periphery of which is divided into two sections, each of said sections being sub-divided into -facets, the lower facets having holes therethrough at ri ht angles to the faces thereof, and a hub formed with the barrel.

, 2. In a device of the character described, a drum the periphery of which is divided into two sections, each of said sections being sub-divided into facets, the lower facets having holes 7 formed therethrough at right In testimony whereof, I have hereunto aflixed my signature.

JOHN Y. KING.
